I’ll leave you with my best wishes for a very happy 2019, and with a copy of the front side of the (paper) greeting card that we’ve sent to our family and friends for the new year:

Mystery integral.

I’m not sure how many people did the computation (if you want to give it a try, you could do some Symbolic Math in Python), but we do have some nerdy friends… I suppose that you get the friends that you deserve… ☺
